장선영 사단법인 미래융합기술연구학회 2021 아시아태평양융합연구교류논문지 Vol.7 No.9

The objectives of this study are to understand the subjectivity of the disabled perceived by nursing students, to describe its characteristics in each type, and to understand the categorization of the disabled, by applying the Q-methodology. A total 15 4th year nursing students who carried out practice in A university, were asked to classify 38 statements. The collected data was analyzed by using the QUANL PC Program. In the results of this study, the nursing students’ perception of the disabled was divided into two factors such as ‘social/policy-level support highlighted type’ and ‘guardian support highlighted type’. In the results of analyzing the subjectivity of the disabled by using the PC QUANL program, there were total two factors, explaining 51.86% of total variance. The factor 1 was 40.25% while the factor 2 was 11.61%. Among total 15 research subjects, ten people belonged to the factor 1, and the rest five people belonged to the factor 2. This study on the subjectivity would be helpful for changing the perception of the disabled in our society. Moreover, it could be utilized as the basic data for the development of differentiated educational programs, by presenting the subjectivity structure and characteristics of each type of perception of the disabled targeting the nursing students as preservice medical personnel.

Mucosal dendritic cells shape mucosal immunity

장선영,고현정,권미나 생화학분자생물학회 2014 Experimental and molecular medicine Vol.46 No.-

Dendritic cells (DCs) are key modulators that shape the immune system. In mucosal tissues, DCs act as surveillance systems to sense infection and also function as professional antigen-presenting cells that stimulate the differentiation of naive T and B cells. On the basis of their molecular expression, DCs can be divided into several subsets with unique functions. In this review, we focus on intestinal DC subsets and their function in bridging the innate signaling and adaptive immune systems to maintain the homeostasis of the intestinal immune environment. We also review the current strategies for manipulating mucosal DCs forthe development of efficient mucosal vaccines to protect against infectious diseases.

대학 모바일 학습에서 영어 말하기 교육의 효과

장선영,김혜진 한국교육방법학회 2011 교육방법연구 Vol.23 No.4

Although mobile devices have been quickly incorporated into language learning for individual studies, EFL classrooms in Korean colleges still are yet to be introduced to accessible teaching methodologies of m-learning. This study is to demonstrate the impact of mobile learning as learning strategies and identified the ways in which metacognitive capabilities operate differently for individual students in m-learning. 81 college students from four classes were participating in this study, and broken down into two groups. The controlled group had classroom lessons and the experimental group took classroom lessons and worked with a mobile device to apply the lesson. A pre- and final-test were conducted to measure the individual change in English proficiency. Two sets of questionnaires were used to gauge the students’ metacognitive levels and students’ satisfactory levels on m-learning. The result of the study shows that using the mobile device in language learning helps improve learners’ learning performance, and that m-learning was more effectively working for students with high metacognitive level. The results indicate that learners were motivated to use mobile devices in their spare time, which benefits their learning. Therefore, the EFL learning can be augmented by integrating informal m-learning into the more traditional learning process. 유비쿼터스 시대에 접어들면서 모바일을 학습에 활용하는 사례가 증가하고 있다. 외국어 학습에서도 모바일 폰을 사용하여 학습자의 동기와 흥미를 자극할만한 효과적인 교수-학습 전략을 개발하는 것은 중요하다. 본 연구에서는 모바일 폰이라는 최신 매체를 활용하여 영어 학습을 향상시키는 교수-학습 방법을 제안하는 데에 목적을 두었으며 학습자의 초인지 능력 수준에 따른 학습 결과에 대해 연구하였다. 연구결과 첫째, 모바일 학습은 영어 말하기 학습과 같은 영역에서도 유의미한 효과 차이가 있었다. 둘째, 초인지 능력 수준에 상관없이 모바일 학습은 모두 효과가 있는 것으로 나타났다. 세부적으로는 초인지가 낮은 학습자에게는 초인지가 높은 학습자와는 달리 필히 구체적인 피드백을 줄 필요가 있고, 초인지가 높은 학습자를 위해서 특히 ‘흥미’를 유발시키는 교수-학습 전략을 제안할 수 있겠다. 또한 초인지가 낮은 학습자를 위해서 수업시간에 배운 영어 표현을 익히게 하는 반복 및 연습과 같은 교수-학습 방법을 제안할 수 있겠다.

WIENER-HOPF C*-ALGEBRAS OF STRONGLY PERFORATED SEMIGROUPS

장선영 대한수학회 2010 대한수학회보 Vol.47 No.6

If the Wiener-Hopf C*-algebra W(G, M) for a discrete group G with a semigroup M has the uniqueness property, then the structure of it is to some extent independent of the choice of isometries on a Hilbert space. In this paper we show that if the Wiener-Hopf C*-algebra W(G, M) of a partially ordered group G with the positive cone M has the uniqueness property, then (G, M) is weakly unperforated. We also prove that the Wiener-Hopf C*-algebra W(Z, M) of subsemigroup M generating the integer group Z is isomorphic to the Toeplitz algebra, but W(Z, M) does not have the uniqueness property except the case M = N.

장선영,신동엽,이은직,최영준,이상렬,윤진숙 연세대학교의과대학 2013 Yonsei medical journal Vol.54 No.4

Purpose: To investigate an association between the levels of serum thyroid-stimulating hormone (TSH)-receptor autoantibodies (TRAbs) and Graves’ orbitopathy (GO) activity/severity scores, and compare the performance of three different TRAb assays in assessing the clinical manifestations of GO. Materials and Methods: Cross-sectional study. Medical records of 155 patients diagnosed with GO between January 2008 and December 2010 were reviewed. GO activity was assessed by clinical activity score (CAS) and severity graded with the modified NOSPECS score by a single observer. Serum TRAb was measured by three different methods: 1st generation thyrotropin-binding inhibitor immunoglobulin (TBII) assay (TRAb1st); 3rd generation TBII assay (TRAb3rd); and biological quantitative assay of thyroid-stimulating immunoglobulin (TSI) using Mc4-CHO cells (Mc4-CHO TSI assay). Results were correlated with scores of activity/severity of thyroid eye disease. Results: All three assays (TRAb1st, TRAb3rd, and Mc4-CHO TSI) yielded results that were significantly positively correlated with CAS (β=0.21, 0.21, and 0.46, respectively; p<0.05) and proptosis (β=0.38, 0.34, and 0.33, respectively;p<0.05). Mc4-CHO TSI bioassay results were significantly positively correlated with all GO severity indices (soft tissue involvement, proptosis, extraocular muscle involvement, and total eye score; β=0.31, 0.33, 0.25, and 0.39, respectively;p<0.05). Conclusion: Mc4-CHO TSI bioassay was superior over the two TBIIs in assessing active inflammation and muscle restriction due to GO, whereas TBII assay would be sufficient for evaluation of patients with proptosis.

외국어 학습에서 학습자의 초인지 능력 및 학습 수준 인식의 정도에 따른 실제 학습 수준과 학습 관련 제반 인식에 관한 연구

장선영,김혜진 한국교육방법학회 2011 교육방법연구 Vol.23 No.2

초인지와 학습의 결과와의 관계를 나타낸 일반적인 학습의 원리를 전제로 교수 전략을 수립하고 실행할 수 있지만 초인지 능력의 정도에 따라 학습의 결과를 예측할 수 없는 경우가 발생할 수 있다. 이에 본 연구는 외국어 학습에서 학습자의 초인지 능력의 정도 및 자기 학습 수준 인식의 정도에 따라 학습자의 실제적인 학습 수준과 학습자의 학습 관련 제반 인식에 어떤 차이가 나타나며, 이것이 복합적으로 고려되었을 때 구체적으로 어떤 차이가 나타나는지를 살펴보았다. 이를 통해 궁극적으로 실질적인 교수-학습의 초인지 전략을 수립하는 데 도움을 주고자 하였다. 일련의 측정도구를 사용한 후 빈도 및 비율 분석, 다변량분산분석(MANOVA) 및 일원배치 분산분석(ANOVA), t검정에 의해 결과를 분석하였고 이때 통계 프로그램 SPSS 12.0을 사용하였다. 연구 결과로 첫째, 학습자의 초인지 능력에 따라 구분된 세 집단 간에는 학습자의 ‘자신감, 재미와 흥미, 뚜렷한 목표, 만족감’이란 학습자의 학습에 대한 인식에서 유의미한 차이가 나타났다. 이들 항목 모두에서 초인지가 ‘상’인 집단이 동기의 중요한 요소인 ‘자신감’ 및 ‘재미와 흥미’, ‘만족감’ 영역에서 높은 점수를 나타냈다. 둘째, 학습자의 자기 학습 수준 인식 집단별로 초인지 능력과 진단평가를 통한 실제 학습 수준에서 모두 유의미한 차이가 나타나지 않았다. 이는 초인지 능력이 예측하는 기존의 결과를 벗어나는 것이었다. 셋째, 초인지 능력의 ‘상․중․하’ 정도에 따라 ‘잘 모르겠음’과 같은 학습 수준 인식의 정도를 해석할 때 주의를 기울여야 할 필요가 있다. 이상의 결론을 토대로 교수-학습 전략 수립에 참고할 내용을 제안하였고 연구의 제한점도 제시하였다. Many studies have argued that meta-cognitive capability has high correlations with learners' learning abilities and results, thereby recommending meta-cognition as an effective teaching and learning strategy. However, various problems occur in classrooms because actual learning level and outcomes are not always in accordance with the learning theories on the relation between meta-cognitive capabilities and learning results in EFL environments. This study purposes to explore how and why learners' meta-cognitive capabilities and learning recognitions are not consistent with their learning levels and learning variables and how these differences affect on their learning processes. This study, thereby, aims to find more practical teaching-learning strategies in language learning. A survey was administered to 111 college students in Korea. The data from the questionnaire were analyzed with SPSS 12.0. One-way ANOVA, MANOVA, and t-test were used to examine the differences among the three groups of meta-cognitive capability (higher, medium, and lower) and the three groups of learning recognition(medium, lower, and ambiguous). The frequencies and percentages of learning recognition were analyzed by the three groups of metacognitive capability. Based on the analysis of the results, the followings are induced. (1) The three meta-cognitive groups exhibit significant differences in confidence, interest, goal, and satisfaction. The higher meta-cognitive group shows the highest score in all three aspects of confidence, interest, and satisfaction. (2) The three learning recognition groups indicate no significant difference in meta-cognition capability and learning level. It is not consistent with the prior researches on meta-cognition. (3) The study gives a special attention to the students with ‘ambiguous’ learning recognition, which generates various meanings. Considering these results, it is urgent to develop more practical teaching-learning strategies concerning learners' learning levels and meta-cognitive capabilities.

장선영,이현준,정문선,김소영 대한안과학회 2009 대한안과학회지 Vol.50 No.8

Purpose: To report a case of acute transient myopic shift in a patient with fever of unknown origin. Case summary: A 31-year-old woman without a history of any ophthalmic problems presented with a sudden onset of bilateral blurred vision. She was admitted with the diagnosis of fever of unknown origin (FUO). Ophthalmic examination revealed a visual acuity of 0.06 in the right eye and 0.1 in the left eye. A myopic shift of 3.12 diopters (D) and 2.25D was noted in the right and left eyes, respectively. Retinal folds and choroidal thickening accompanied the myopic shift. On the third day after onset, visual acuity had decreased even more. Myopic shift increased to 4.87D in the right eye and 4.50D in the left eye. At the same time, the depth of the anterior chamber maximally decreased and the thickness of the lens was maximally increased. One week later, the myopic shift was normalized to emmetropia. The depth of the anterior chamber and the thickness of the lens also normalized as the fever subsided. 목적: 불명열 환자에서 동반된 급격한 근시성 굴절력 변화 1예를 경험하여 이를 보고하고자 한다. 증례요약: 안과적 과거력이 없는 31세 여자가 불명열로 치료하던 중 갑자기 발생한 양안의 시력저하를 주소로 안과에 의뢰되었다. 처음 검사에서 나안시력은 우안 0.06, 좌안 0.1이었으며 현성굴절검사에서 우안 -3.12Diopters(D), 좌안 -2.25D의 근시성 굴절이상을 보였다. 안저검사에서 망막 주름, 초음파 검사에서 맥락막 부종의 소견이 동반되었다. Pentacam과 A-scan을 이용하여 전방깊이, 수 정체 두께 및 안축장을 측정하였고 매 검사 시마다 추적 관찰했다. 증상 발생 3일째에 시력은 더욱 감소하였으며 우안-4.87D, 좌안 -4.50D로 근시성 굴절이상이 증가하였고 전방 깊이는 더욱 감소되었고 수정체 두께는 증가되었다. 증상 발생 1주일 후 내과적인 증상 이 호전되면서 굴절이상은 정시화되었고 전방 깊이 및 수정체의 두께도 정상화 되었으며 나안시력은 양안 1.0으로 호전되었다.

기본형 간헐외사시에서 수술 전 단안차폐 후 사시각 측정의 의미

장선영,이자영,박성희,김소영 대한안과학회 2009 대한안과학회지 Vol.50 No.9

목적: 기본형 간헐외사시의 수술 전 1시간 단안차폐 후 사시각 측정의 의미를 알아보고자 하였다. 대상과 방법: 기본형 간헐외사시로 수술 받은 환아 중 수술 전 단안차폐검사를 시행한 29명을 대상으로 후향적으로 조사하였다(단안차 폐군). 1시간 단안차폐 후 원거리에서 사시각이 재 측정되었으며 사시각이 증가한 경우 측정된 사시각을 목표로 수술이 시행되었다. 수술 전 단안차폐검사를 하지 않았던 환아 중 대상군과 연령, 성별 및 융합상태가 유사한 29명의 환아를 대조군으로 하였으며 6개월 이상 추적관찰 하였을 때 수술 결과를 비교하였다. 결과: 단안차폐군 29명 중 15명(51.7%)에서 사시각의 증가가 관찰되었으며 융합상태가 나빴던 15명 중 4명(26.7%), 융합상태가 좋았던 14명 중 11명(78.6%)에서 사시각의 증가가 있었다(p<0.05). 수술 성공률은 단안차폐군 79.3%, 대조군 75.9%로 유의한 차이는 없었으나 융합 상태가 좋았던 환아의 수술 성공률은 각각 85.7%, 71.46%로 단안차폐군에서 수술 성공률이 높았으나 통계학적으로 유의하지는 않았다 (p=0.357). 결론: 융합상태가 좋은 기본형 간헐외사시에서 수술 전 단안차폐를 시행하는 것은 잠재되어 있는 사시각을 찾아주어 수술 후에 발생하는 부족교정을 예방하는데 도움을 줄 수 있을 것이다. Purpose: To assess the clinical potential of one‐hour monocular occlusion on preoperative alignment evaluation in basic intermittent exotropia. Methods: Twenty-nine patients with basic intermittent exotropia who were preoperatively examined for one‐hour monocular occlusion were selected (monocular occlusion group). Their records were reviewed retrospectively. The measured angle after one hour of monocular occlusion was used to determine the surgical target angle. The control group consisted of 29 patients whose age, sex and control state were similar to the monocular occlusion group. Measurement of the angle of strabismus was not done in the control group. Surgery was performed for the measured angle at six meters. The results of surgery were used to compare the groups relative to the control state. Results: Fifteen patients (51.7%) had an increase in the distance deviation after one hour of monocular occlusion. Of the patients with good control, 78.6% (11/14) had an increase in the angle of misalignment. Only 26.7% (4/15) of patients with poor control experienced a change in the angle deviation (p<0.05). In all, 79.3% of patients in the study group and 75.9% of those in the control group had a satisfactory surgical outcome. Among the patients with good control, 85.7% of patients who underwent surgery for increased angle had a satisfactory outcome, compared with 71.4% of patients who underwent surgery for initial angle (p=0.375). Conclusions: One-hour monocular occlusion might help to prevent undercorrection after surgical treatment by identifying the hidden deviation, especially in the patients whose control over the distance deviation was good.
