A Novel Approach for Bolted T-Stub Connections
Merve Sağıroğlu,Mahyar Maali,Mahmut Kılıç,Abdulkadir Cüneyt Aydın 한국강구조학회 2018 International Journal of Steel Structures Vol.18 No.3
This paper reports an investigation into new connection types and their behaviors determined using full-scale experiments. T-shaped connections were created using the IPE standard profi le. The aim of this study was to analyze the infl uence of T connections based on the IPE standard profi le, height of beam to height of T-stub joint (H) of T-stub joints, and lengths (X) of T-stub joints on the behavior of steel connections, in order to provide the necessary data for improving Eurocode 3 and enable effi cient use of residue IPE standard profi les and back to the consumption cycle. While the moment resistance values increased with an increase in H from H min to H max in model groups with X of 126 mm, and the energy dissipation increased with an increase in H from H min to H max and also with an increase in the lengths (X) of T-stub joints from 54 to 126 mm.

( Ro Sa Kim ),( Bo Ram Kwon ),( Hae Young Choi ),( You Won Choi ),( Min Young Lee ),( Ji Yeon Byun ) 대한피부과학회 2019 대한피부과학회 학술발표대회집 Vol.71 No.1
Giant cell tumor of tendon sheath (GCTTS) is a second most common tumor of the hand following the ganglion cyst. It presents a slowly growing subcutaneous nodule in the finger encapsulated by a collagenous capsule. GCTTS has benign course mostly with diagnosed as a localized form, but rare cases of malignant GCTTS have been reported. As incomplete excision increases recurrence rate and on recurrence the possibility of malignant transformation also increases. The average age of onset of GCTTS is middle-aged adults and the prevalent site is the volar surface of finger. An 85-year-old Korean female presented with skin colored hard nodule on dorsal surface of left 3rd DIP joint of finger, a slowly enlarging for several years. Histological examination showed a well encapsulated round lobule in the dermis with varied cellularity. The mass consisted of many mononuclear cells and spindle cells in fibrous stroma, and osteoclast-like giant cells and foamy macrophages were characteristic. There was no specific finding in the Von-Kossa stain and the level of serum uric acid was normal. The patient was diagnosed with GCTTS and referred to an orthopedic surgeon for an excision surgery. Herein, we report a rare case of GCTTS occurring in old age on dorsal surface of finger.

Using Internet Video Clips for University Students` Vocabulary Development in Blended Learning
( Ro Sa Jung ),( Chung Hyun Lee ) 한국멀티미디어언어교육학회 2013 멀티미디어 언어교육 Vol.16 No.4
The purposes of the study are to investigate the impact of using video clips on university students` vocabulary development via listening in blended learning and to suggest a vocabulary instructional model for the use of video clips in blended learning. Twenty one students participated in L2 listening classes at A university in Seoul. A combination of qualitative data from students` reflective journals, classroom observations, and interviews and quantitative data from pre- and post- vocabulary tests, performance assessment, and a questionnaire was collected. The major findings of the study are as follows. First, about 55% of the students guessed the meaning of the words with visual, contextual, and verbal clues from video clips. Second, the students` overall perspectives on using video clips for learning vocabulary in blended learning were very positive. Third, the students had generally positive perspectives on online and offline activities. Guessing the meaning of the words and filling out the summary were the most preferred offline and online activities, respectively. Finally, the students` vocabulary test scores increased indicating that using video clips in blended learning had positive effects on students` vocabulary development. Based on the findings, a vocabulary instructional model as well as implications are provided.

클라이언트 자살행동에 개입한 사회복지사의 외상 후 성장 영향요인: 사회복지기관별 비교
박로사 ( Ro-sa Park ),최송식 ( Song-sik Choi ) 경남대학교 인문과학연구소 2019 人文論叢 Vol.49 No.-
본 연구는 사회복지사에게 노출되어있는 다양한 외상 중, 클라이언트 자살행동에 개입한 사회복지사를 대상으로 개인적, 가족적, 조직적 요인이 외상 후 성장에 미치는 영향을 살펴보고자 하였다. 이를 위해 부산광역시의 사회복지기관영역, 정신건강영역, 공적사회복지영역에서 근무하는 사회복지사를 대상으로 자료를 수집하여 분석하였다. 분석결과, 첫째, 연구대상자인 사회복지사는 자살 관련 외상에 자주 노출되었으며, 외상 후 성장 수준은 선행연구에 비해 낮은 수준으로 나타났다. 둘째, 사회복지사 세 영역 전반을 대상으로 회귀분석을 실시한 결과, 자아탄력성과 슈퍼비전이 외상 후 성장에 유의미한 정적 영향이 나타났다. 셋째, 사회복지 영역별 회귀분석을 각각 실시한 결과, 자아탄력성은 세 영역 모두에서 외상 후 성장에 유의미한 정적 영향이 나타났다. 가족응집력은 정신건강영역에서만 유의미한 정적 영향이 나타났다. 결론에서는 이러한 연구결과를 바탕으로 사회복지사의 외상 후 성장을 높이기 위한 개입방향 및 실천적 함의를 논의하였다. Among various types of traumatic events exposed to social workers, this research examines factors affecting post-traumatic growth of social workers who intervened in client suicidal behaviors. As the factors affecting post-traumatic growth, individual factor, family factor, and organizational factor to examine how these factors affect post-traumatic growth. The data were collected from social workers working in sectors of social welfare institution, mental health, and public social welfare in Busan. Statistical analysis was conducted based on the collected data. First, the social workers demonstrated frequently exposed to suicide related trauma risks and level of post-traumatic growth was lower than that of previous studies. Second, as a result of conducting a regression analysis of three sectors on social workers, ego-resiliency and supervision had a significantly positive impact on post-traumatic growth. Third, as a result of conducting a regression analysis between the social workers sectors, ego-resiliency had a significantly positive impact on post-traumatic growth in all three sectors. In terms of family cohesion, it had a significantly positive impact only in the mental health sector. Supervision had a significantly positive impact in the social welfare institution and public social welfare sections. Based on findings, we discussed the direction of intervention and practical implications for improving post-traumatic growth of social workers.
