Students who speak languages other than English comprise a growing population in U.S. schools. As a result, many general education teachers find English language learners (ELLs) in their mainstream classrooms. However, they are often inadequately prepared to work with culturally and linguistically diverse students, resulting in a need for better ELL preparation of mainstream teachers (de Jong & Harper, 2005). Teacher self-efficacy beliefs (TSEB), or teacher perceptions of their confidence and preparedness, can provide important insights relevant to teacher professional development and preparation in teacher education programs. TSEB is defined as a self-assessment of the competence to perform a specific task within a certain context, or a judgement of the ability to perform a desired activity (Tschannen-Moran & Hoy, 2001). Recognizing the importance of investigating TSEB, this dissertation examines elementary preservice teachers and their preparation to work with ELLs through microteaching activities. Two research questions guided this study: 1) What are the self-efficacy beliefs of preservice teachers about teaching ELLs before and after microteaching experiences, and 2) how do four preservice teachers construct their self-efficacy beliefs regarding teaching ELLs through microteaching experiences? The data—consisting of surveys (n=55), individual interviews with preservice teachers (n=4), classroom observations and lesson plans—were analyzed with the use of thematic analysis (Braun & Clarke, 2006). Findings indicated that the self-efficacy beliefs of preservice teachers were enhanced after having participated in ESL microteaching experiences. However, the data also revealed that the preservice teachers still felt some anxiety and emotional concerns about teaching ELLs. Moreover, their self-efficacy beliefs varied by ELL characteristics (situational factors) and setting (contextual factors). Results further revealed that three factors shaped the construction of TSEB, namely ELL-related knowledge from course work, field experiences working with ELLs, personal and professional exposure to linguistic and cultural diversity, including their own language learning experiences. Inquiries about the influence of purposeful field placements and ESL microteaching experiences for teacher candidates in settings with culturally and linguistically diverse students can yield valuable insights. Future studies of teacher preparation coursework for preservice teachers that embed linguistically responsive theories and practices can inform teacher candidates as they strive to enhance their preparation and self-efficacy beliefs for ELLs (Lucas & Villegas, 2013).

Accurate anatomical reduction, rigid internal fixation and early mobilization are essential for good prognosis especially in the intraarticular fractures. Fractures of the calcaneus involving the subtalar joint have controversy for treatment method because of the anatomical complexity and hence difficulty of accurate reduction and rigid internal fixation. We analyzed 26 cases (15 males, 6 females) of the calcaneal fractures involving the subtaler joint, which were treated by open reduction and internal fixation from May, 1992 to Feb., 1995 in Asan Medical Center. The average follow-up period was 18.3 months ranged from two to forty three months. According to the Essex-Lopresti classification, there were 12 cases of joint depression type, 11 cases of tongue type, and 3 cases of comminuted type. In 10 cases which were evaluated with CT scan, there were 4 cases of type Ⅱ, 4 cases of type Ⅲ, and 2 cases of type Ⅳ according to the Sander's classification. We used the extensive lateral approach and applied cervical H-plate or reconstruction plate in most cases for internal fixation. The results of the treatment were obtained as followed ; Bohler angle was recovered on the average 27.0°from -3.5°preoperatively to 23.5°postoperatively ; Gissane angle, 0.5°from 119.1°to 119.6°; the height of heel, 19% to 96% and the width of the calcaneus was reduced 16% to 105% of contralateral one respectively. The functional results of operation were good or excellent, but those of severely comminuted type were unsatisfactory. We concluded that the fractures of the calcaneus are still unsolved problem, but should be managed in the principle of the treatment of the intraarticular fracture, and this can be done through the extensive lateral approach with ease and safe.

『박소촌화』 所載 <마포유일정> 연구

이병직(Lee, Byong-Jik) 부산대학교 한국민족문화연구소 2012 한국민족문화 Vol.43 No.-

이 글은 18세기 여러 야담집을 비롯하여 각종 문헌에 수록된 강상효녀담의 하나인 <마포>를 중심으로 작품의 형성 시기와 창작의식을 검토하고 서사문학적 의미를 밝히는데 목적을 두었다. 강상효녀담은 1709년 무렵 형성되었다고 알려져 있으나 이동윤의 <마포>에 기록된 관련 정보를 근거로 할 때 1700년을 전후하여 성립하였을 가능성이 있다. <마포>의 사건 내용은 초기 강상효녀담인 이홍덕의 전과 유사하며, 강상효녀의 효열과 시비의 충렬을 기린다는 목적 또한 동일하다. 하지만 <마포>에서는 여아의 의리를 문제삼는 것에서 더 나아가 작품에 등장하는 관련인물을 평가하는 것으로 내용을 확대하였다. 이동윤은 <마포>를 통해 노론 우위의 당파적 입장을 분명히 하였고, 관련 인물인 정유악의 비판과 이천기의 옹호를 통해 의리 문제를 강조하기 위해 강상효녀담을 적절하게 이용하였다고 볼 수 있다. <마포>를 비롯한 강상효녀담은 문헌과 구연 등 다양한 전승경로가 있다. 초기 강상효녀를 다룬 작품에서는 ‘복수’를 완성한 여주인공의 절행에 초점이 맞추어져 있지만, 후대로 갈수록 수용하는 사람의 취향이나 기록자의 지향가치에 따라 내용에서 다양한 변이가 일어났다. <마포>는 강상효녀담의 형성 시기, 창작의식을 검토하기 위한 자료로서의 의의를 가질 뿐만 아니라 개별 작품이 어떤 구연 과정을 거쳐 문헌에 정착되는가 하는 점, 이 과정에서 이야기꾼으로서의 존재 가능성을 엿볼 수 있다는 점에서 서사문학적 의미를 갖는다고 할 수 있다. This thesis is supposed to clarify the birth period of work, creative motive, and the meaning of epic literacy focused on <Mafo>, which is one of GangSang filial daughter stories collected in many writings. It is said that GangSang filial daughter stories were formed around 1709. But we can guess they could be formed judging in 1700 from the basis of <Mafo> written by Lee DongYoon. The story of <Mafo> was similar to that of GangSang filial daughter in the early time. And in the terms of commemorating a daughter"s filial piety and a servant"s unswerving loyalty, it seems that these two had similar intention. But <Mafo> had enlarged the daughter"s obligation more seriously. Lee DongYoon clarified the faction attitude of conservative party through <Mafo>. Also he emphasized obligation matter by criticizing Jong YooAk and defending Lee CheonGee. GangSang filial daughter stories like <Mafo> have been passed through literature works and oral narration. Especially, as time goes by, these stories have changed a lot by the people"s aptitude and writers" directivity value. <Mafo> has special meaning as a data to search for the originating time and creative motive of GangSang filial daughter stories. We can figure out that this work has a big epic literature meaning because the writer of this story had potential as a storyteller and how each work could be passed and settled in literature documents.

Background/Aims: The aim of this study was to evaluate the outcome of endoscopic dilation for benign anastomotic stricture after radical gastrectomy in gastric cancer patients. Methods: Gastric cancer patients who underwent endoscopic balloon dilation for benign anastomosis stricture after radical gastrectomy during a 6-year period were reviewed retrospectively. Results: Twenty-one patients developed benign strictures at the site of anastomosis. The majority of strictures occurred within 1 year after surgery (95.2%). The median duration to stenosis after surgery was 1.70 months (range, 0.17 to 23.97 months). The success rate of the first endoscopic dilation was 61.9%. Between the restenosis group (n=8) and the no restenosis group (n=13), there were no significant differences in the body mass index (22.82 kg/m2 vs 22.46 kg/m2), interval to symptom onset (73.9 days vs 109.3 days), interval to treatment (84.6 days vs 115.6 days), maximal balloon diameter (14.12 mm vs 15.62 mm), number of balloon dilation sessions (1.75 vs 1.31), location of gastric cancer or type of surgery. One patient required surgery because of stricture refractory to repeated dilation. Conclusions: Endoscopic dilation is a highly effective treatment for benign anastomotic strictures after radical gastrectomy for gastric cancer and should be considered a primary intervention prior to proceeding with surgical revision.

손병직 ( Son Byung-jik ),이규환 ( Lee Kyu-hwan ) 한국복합신소재구조학회 2020 복합신소재구조학회논문집 Vol.11 No.6

저해상도 하수관거의 균열을 탐지하기 위해서 웨이블릿 기법을 이용하여 연구를 수행하였다. 변수 4개를 설정하여 파라미터 연구를 수행하였으며 기존 CNN 기법의 연구와 비교를 통해 타당성을 검증하였다. 연구 결과 본 연구에 제시된 파라미터 변수들의 기본값만 사용하더라도 97.2%의 높은 정확도를 나타내었으며, 정확도가 들쭉날쭉하지 않고 안정성을 나타내었다. 따라서, 웨이블릿 기법을 활용하여 구조물의 균열 등 결함 인식 등의 문제를 잘 해결할 것으로 판단되며 향후 연구로 딥러닝 기법과의 상호 보완적인 방법을 모색하고자 한다. In this study, the wavelet technique was used to detect cracks in low-resolution sewage pipes. A parameter study was conducted using four variables, and the validity was verified by comparing the results of the wavelet technique with those of the currently used CNN technique. The results show that, even if only the default values of the parameter variables presented in this study are used, the accuracy is 97.2%, is not jagged, and shows stability. As such, the wavelet technique can be used to recognize defects like cracks in structures. Future research should seek a complementary method that uses the deep learning technique.

Effect of Insam Saponin on the Absorption of Glucose and Tyrosine

Lee, Sang Jik,Kim, Dong Soon 嶺南大學校附設 基礎科學硏究所 1982 基礎科學硏究 Vol.2 No.-

Saponins, as one of the major components of insam root, attracted much concern of investigators in physiological and pharmaceutical fields since they were seprated from panax quinquefolium L. by Garriques in 1854. Biochemical approaches involving examination of saponin-biomenbrane interaction possibly 엳 새 surface activity (Lee et al., 1981) of the saponin have been conducted in this laboratory. It was reasonably suggested that insam saponin interacted with free lipid molecules because of its surface activity and solubilized them in the aqueous media (Joo and Lee, 1977). In this respect, biomembrane consisting largely of lipid molecules will be affected somhow by the action of saponin and will show altered functions such as transport phenomenon.
